Bug ID: 271113
Summary: [zfs][loader] it should be possible to see zpool
devices found for loader mountroot stage
Product: Base System
Version: 13.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]

If the boot zpool fails to mount early one, this is painful to
diagnose, mostly yielding "Error 6" and not much else for a user
to deal with.
An off-by-default loader tunable that spits out device tasting
and zpools it locates would help a lot.
No particular reason for it being off-by-default other than on
large multi-device pools it could slow down boot a lot if we
print out all the things.
Specific problem encountered was a zpool where there were
traces of a previous zpool on /dev/da0 & /dev/da1 even
though the current pool was /dev/da0p3 /devda1p3 both called
zroot, and zfs 13.2-RELEASE loader could not decide which
one to import.
Displaying enumerating each label, pool guid, hostid, hostname,
for each device found would be very very useful.
zfs: /dev/da1 label2 pool_guid: 1234 hostid: 6788 hostname: 'example.org'
zfs: /dev/da1p3 label0 pool_guid: 2345 hostid: 7890 hostname: 'example.net'
